The Internal Revenue Service announced that it is generally waiving the penalty for any taxpayer who paid at least 85 percent of their total 2018 tax liability during the year through federal income tax withholding, quarterly estimated tax payments or a combination of the two. The usual percentage threshold is 90 percent to avoid a penalty.

This relief is designed to help taxpayers who were unable to properly adjust their withholding and estimated tax payments to reflect an array of changes under the Tax Cuts and Jobs Act (TCJA), the far-reaching tax reform law enacted in December 2017.

“We realize there were many changes that affected people last year, and this penalty waiver will help taxpayers who inadvertently didn’t have enough tax withheld,” said IRS Commissioner Chuck Rettig. “We urge people to check their withholding again this year to make sure they are having the right amount of tax withheld for 2019.”

The updated federal tax withholding tables, released in early 2018, largely reflected the lower tax rates and the increased standard deduction brought about by the new law. This generally meant taxpayers had less tax withheld in 2018 and saw more in their paychecks.

However, the withholding tables couldn’t fully factor in other changes, such as the suspension of dependency exemptions and reduced itemized deductions. As a result, some taxpayers could have paid too little tax during the year, if they did not submit a properly-revised W-4 withholding form to their employer or increase their estimated tax payments.

Additional Information

Because the U.S. tax system is pay-as-you-go, taxpayers are required, by law, to pay most of their tax obligation during the year, rather than at the end of the year. This can be done by either having tax withheld from paychecks or pension payments, or by making estimated tax payments.

Usually, a penalty applies at tax filing if too little is paid during the year. Normally, the penalty would not apply for 2018 if tax payments during the year met one of the following tests:

The person’s tax payments were at least 90 percent of the tax liability for 2018 or

The person’s tax payments were at least 100 percent of the prior year’s tax liability, in this case from 2017. However, the 100 percent threshold is increased to 110 percent if a taxpayer’s adjusted gross income is more than $150,000, or $75,000 if married and filing a separate return.

For waiver purposes only, this new relief lowers the 90 percent threshold to 85 percent. This means that a taxpayer will not owe a penalty if they paid at least 85 percent of their total 2018 tax liability. If the taxpayer paid less than 85 percent, then they are not eligible for the waiver and the penalty will be calculated as it normally would be, using the 90 percent threshold.

Like last year, the IRS urges everyone to check their withholding for 2019. This is especially important for anyone now facing an unexpected tax bill when they file. This is also an important step for those who made withholding adjustments in 2018 or had a major life change to ensure the right tax is still being withheld. Those most at risk of having too little tax withheld from their pay include taxpayers who itemized in the past but now take the increased standard deduction, as well as two-wage-earner households, employees with nonwage sources of income and those with complex tax situations.
